Oil-cup for journal-boxes



PATENTED JULY 29, 1851 RICHARDSON. OIL GUP FOR JOURNAL BOXES.

AARON RICHARDSON, OF BELLOWS FALLS, VERMONT.

OIL-CUP ron JOURNAL-BOXES.

Specification of Letters Patent No. 8,251,:1atedJu1y 29, 1851.

To. all whom it may concern:

Be it known that I, AARON RICHARDSON, of Bellows Falls, in the county ofWindham and State of Vermont, have invented a new and useful Improvementin Oil-Cups for Lubricating the Journals or other Bearings or RubbingSurfaces of Machinery; and I do hereby declare that the following is afull, clear, andexact description "of the same, referencebeing had tothe accompanying drawings, forming part ofthis specification, in which--Figure 1, is a side view of one of the cups and Figs. 2, and 3, arevertical sections through the center.

Similar letters of reference indicate corresponding parts in each of theseveral figures.

My'invention consistsin providingthe interior of the oil cup, with avalve, which fits in a seat around the mouth and is held there by aspring; serving to close the mouth of l the cupand exclude dirt butyielding to the slightest pressure of the spout of an oil can or feeder,and allowing the oil or other lubricating material to be introduced;closing itself when the pressure is removed and forming in fact a selfacting stopple. i

To enable those skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

A, represents thebody of the cup which has a screw socketmmat itsbottom, fort-he purpose of screwing it into the cap of a journal box, oranybearing in which it isto be used. Its external form may be any thatis considered desirable,.but its mouth I), is contracted or madesmallerthan the part of the inside below it,to form a valveseat.

B, is a spherical valve fitting within the valve seat 6. Any otherdescription of valve may be used but Iconsider this form p the best asit will morereadily find its place.

C, is a spiral spring within the cup. This and the valve are insertedthrough the bottom of the cup, and are-kept in by a ring D, which isscrewedinto the bottom or socket a, and forms a bearing for the spring,which valve or spring, but

described.

presses under the valve and causes it to keep the mouth I closed (asshown in Fig. 2,) when it is not opened by some external or downwardpressure. a

The oil is fed into the cup by simply pressing the spout of the feeder(as shown in Fig. 3) upon the upper surface of the valve, which may ormay not project above the mouth when closed, the spring requiring to beonly strong enough to hold the valve in place, yields readily to thepressure, and allows the valve to descend sufiiciently to admit the oilto the inside, and on the feeder being withdrawn it raises the valve andcloses the entrance. A wick may be used within the cupif thoughtdesirable to prevent the oil escaping too freely to the bearing.

This oil cup possesses one great advantage overt-he oil cup in commonuse, as many bearings are placed in such positions that when themachineryof which they form part is in motion, it is difficult to removetheir st-opples, while thismay be opened by a long spouted feeder, wherethe hand could not reach. Another advantage is that it will beimpossible to leave it open as is sometimes. done by forgetfulness, tothe detriment of machinery. For locomotive engines I consider itparticularly well adapted, as it will exclude the dirt and dust whichare so destructive, and will allow the engineerto. oil his bearings withone hand while the engine is running.

I. do not confine myself to any form of What l-clalm as my invention anddesire to secure by Letters Patent, is.

The employment within the mouth ofan oil cup of a valve B, operated uponby a spring C, or its equivalent in the manner and for the purposesubstantially as herein AARON RICHARDSON. Witnesses: a Q
